Dunk City is long gone. Make way for the next bracket buster from the little-known Atlantic Sun Conference: Mercer.

The 8,300-student school from Macon, Ga., delivered the biggest shocker in an already topsy-turvy NCAA Tournament on Friday, going into Duke's backyard and knocking off the No. 3 seed Blue Devils 78-71 in Raleigh, N.C.

"This is what March Madness is all about," Atlantic Sun Player of the Year Langston Hall said.

The 14th-seeded Bears - with a starting lineup of five seniors - came back from five points down in the last 4:52 as Duke's offense collapsed.

Mercer qualified for its first NCAA Tournament since 1985 by winning the Atlantic Sun conference championship over Florida Gulf Coast, nicknamed "Dunk City" for the team's above-the-rim offense. A year earlier, the Bears lost that game and watched Florida Gulf Coast advance to the Sweet 16.

"When they were going on their run, we were sitting at home thinking, 'Man, that could have been us,' " Anthony White Jr. said.

Mercer scored 11 straight points during the late 20-5 run that clinched the biggest victory in school history and sent the Blue Devils to their second first-game exit in three years.

But the Blue Devils' defense - an uncharacteristic weakness all season - did them in again while all those Mercer seniors simply got any shot they wanted. The Bears shot 56 percent - 58 percent in the second half.

Duke went up 63-58 with 4:52 left after Parker converted a three-point play and Tyler Thornton hit three free throws.

The Blue Devils didn't score again until the final minute.

"I don't know if we panicked," senior Andre Dawkins said, "but we didn't do the things we needed to do."
